Clemastine

(+)-(2R)-2-(2-(((R)-p-Chloro-alpha-methyl-alpha-phenylbenzyl)oxy)ethyl)-1-methylpyrrolidine

C21H26ClNO (343.1703)

Clemastine is only found in individuals that have used or taken this drug. It is an ethanolamine-derivative, first generation histamine H1 antagonist used in hay fever, rhinitis, allergic skin conditions, and pruritus. It causes drowsiness. [PubChem]Clemastine is a selective histamine H1 antagonist and binds to the histamine H1 receptor. This blocks the action of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms brought on by histamine.
